Definitions
- the invention relates to a steering axle, in particular trailing steering axle for a trailer vehicle, with an axle body terminating in an axle fist and a steering arm articulated by means of a bolt under the axle fist to the vehicle wheel.
- a steering axle with these features is from the EP 0 432 519 A1 known.
- This is a forced steering system in which the steering movement is transmitted to the steering knuckle articulated on the axle body via a centrally arranged hydraulic cylinder and tie rods.
- the construction of the steering axle is relatively simple, in that the steering arm, on which the respective vehicle wheel is mounted, is freely rotatably supported from underneath against the outer end of the axle body designed as an axle fist. The connection of the parts rotatable to each other by a screw on the top of the axle fist.
- Steering axles are also already known with a stabilizing device arranged between the axle body and the wheels and acting in relation to steering angle deflections.
- a stabilizing device arranged between the axle body and the wheels and acting in relation to steering angle deflections.
- Such so-called Nachlauflenkachsen are for example in the EP 0 246 461 B1 or the DE 203 04 107 U1 disclosed.
- the axle fist is here embraced by a fork-shaped steering arm, wherein serving as a pivot bearing bolt extending through both leg portions of the fork-shaped steering arm, as well as through the axle fist.
- the corresponding contact surfaces of the pressure plates are designed as wave profiles, whereby the shaft profiles rotate with increasing angle of rotation of the vehicle wheel to each other, and so changed the axial distance between the axle stub and the fork of the steering arm. It comes to a retreating moment and thus to the desired self-stabilization of the trailing steering axle.
- the trailing steering axle after the EP 0 246 461 B1 is structurally complex with a large number of individual parts. Disadvantages are also in the assembly and disassembly of the pivot bearing between the steering knuckle and steering knuckle.
- the bolt sitting firmly in the axle fist can not be easily removed so as to reach the wear-prone pressure disks.
- the replacement of the pressure plates is particularly affected by the cramped structural situation between the two fork legs of the steering arm. This leads to high assembly and maintenance costs.
- a steering axle according to the preamble of claim 1 is in WO 2004/048180 disclosed.
- the support of the bolt from above preferably takes place against the axle fist. It is further preferred that one of the two supports of the bolt takes place with the interposition of an axially compressible spring element, and that one of the two supports is a thrust bearing.
- the steering axis of the bolt is provided for its axial support at one end with a thread on which a nut is screwed, wherein the nut is supported from the outside against the spring element.
- the preload force acting on the spring element via the nut can be preselected depending on the respective axle type or vehicle type, before the nut is finally fixed by means of a suitable rotation lock.
- a screw can be used instead of the nut, which then engages in a corresponding internal thread of the bolt.
- the nut itself may be provided with means for limiting the maximum tightening torque.
- Such a torque nut is, however, in the execution as a central axle nut, from the EP 1 131 214 A1 known. The same effect can also be achieved by using a screw as a screw.
- the wave profiles is proposed with a further embodiment that they are formed on two mutually supporting pressure plates, and that the pressure plates are the same shape.
- the vehicle counteracting the turning of the vehicle is dependent on the increase of the individual flanks of the wave profile, so that only on the geometry of such a corrugated profile for different applications and different Einlenkeigenschaften the trailing steering axle can be fixed.
- corrugated profiles of lesser pitch can be used than in applications with less heavy goods to be transported.
- the rotary bearing is located within the steering arm, and that the bolt is a weight-reduced hollow bolt.
- the ratio of the height of the pivot bearing to its diameter should be less than 2.
- Optimal is a ratio of 1.5 plus / minus 0.2.
- the steering axle in which the axle body is cranked in the vertical direction in the region of the transition to the axle fist.
- Such cranking has great advantages in terms of the height of the steering axle, which in turn results in advantages for the design of the vehicles formed with the steering axle, e.g. in terms of vehicle height.
- the size of the offset of the axle body is chosen so that the wave profiles are at the height of about half the height of the Achs stressesqueriteses.
- Fig. 1 shows only the outer part of the trailing steering axle. Essentially, this consists of an axle body 3, which is adjoined externally by a stub axle 13, a steering arm 1 for receiving the wheel hub and the wheel, a spring element 5, a bolt 2 and a thrust bearing 4.
- the steering arm 1 is formed according to the invention one arm, and differs from fork-shaped steering knuckles, as they are known from the prior art for trailing steering axles.
- the steering arm 1 is therefore arranged under the axis fist formed at the end of the axle body 13, between them is the pressure bearing 4 explained in more detail below.
- the pivot bearing of the steering arm can be realized with a relatively low overall height.
- this design comes with a low number of parts and is particularly easy to install. To replace the wearing parts, it is not necessary to first pull out the hinge pin 2.
- the thrust bearing 4 is formed by two mutually rotatable shaft profiles 4a, 4b, which in the embodiment according to Fig. 1 be on two identically shaped discs, but also integrally on the steering arm 1 and the axle 13 may be formed.
- the disk carrying the shaft profile 4 a is arranged in a manner secured against rotation with respect to the axle fist 13.
- the shaft profile 4b bearing disc is secured against rotation on the steering arm 1.
- spring element 5 made of rubber or elastomer is increasingly compressed. Accordingly, the restoring force increases at the thrust bearing formed by the shaft profiles 4a, 4b.
- the maximum deflection of the spring element 5 can also serve as a stroke limitation, wherein the maximum compression travel is smaller than the height of the opposite wave peaks of the wave profiles 4 a, 4 b, in order to exclude over-turning of two wave peaks. Turning over two peaks, the feedback would not be possible according to the invention.
- continuous bolt 2 is pressed against rotation in the axle fist 13 of the axle body 3 and is located with a located at one end radially enlarged collar from above to an end face of the axle fist 13.
- the bolt 2 has a reduced diameter threaded portion 14, on which the nut 6 is screwed and so the spring element 5 is secured and biased.
- Above its threaded portion 14 of the bolt 2 is mounted within the steering arm 1 via a dry sliding bearing 7.
- the lateral surface of the bolt 2 which is in rotary contact with the dry sliding bearing is of high surface quality, at least in the area of the dry bearing 7 and corresponding to the maximum stroke of the thrust bearing 4. Since the dry sliding bearing 7 is operated without additional lubricant, the steering pin is designed corrosion resistant in this area, since the otherwise achieved by the lubricant corrosion protection is eliminated.
- the dry sliding bearing 7 consists essentially of a mechanical stability of the dry sliding bearing 7 determining sleeve 9, a inside of the sleeve by a PTFE sleeve (polytetrafluoroethylene) formed sliding layer 8 and two at the front ends of the dry sliding bearing 7 arranged sealing rings 10a, 10b.
- the existing metal sleeve 9 is seated by press fit in the bore of the steering arm first
- the seated in the sleeve 9 sliding layer 8 is formed by a one- or two-piece PTFE sleeve, since PTFE is suitable for such use due to its material properties in a special way.
- the surface of the PTFE sleeve is of high quality, as a result of which the already low static friction values of the PTFE sleeve are very small compared with the region of the lateral surface of the bolt 2 which also marks the sliding partner and is characterized by a high surface quality. Due to the excellent long-term temperature resistance of the PTFE material such dry sliding bearings 7 over a temperature range of -50 to 140 ° C are operable.
- the dry sliding layer may also be other plastics, e.g. all dry-running properties of plastomers and thermosets.
- the sealing rings 10a, 10b are clamped axially fixed between the end face of the sliding layer 8 and a flanging the propositionhüllle 9. Further, protruding lips are formed on the sealing rings 10a, 10b in the direction of the lateral surface of the bolt 2, which constitute an effective securing of the sliding bearing against contamination during the rotational and axial movement of the bolt 2.
- the bolt 2 While the bolt 2 is supported from below via the threaded portion 14, the nut 6 and the spring element 5 against the housing of the steering arm 1, the bolt 2 is supported from above on the axle stub 13.
- the bolt 2 is provided at the upper end with a firmly formed radial collar 15. Since a relative movement occurs between the spring element 5 and the underside of the housing of the steering knuckle 1, there is another thrust bearing 16, preferably a flat Axialgleitlager.
- Integral part of the steering arm 1 are various structural elements, as they are needed in connection with the wheel and the wheel brake. These are in addition to the actual journal 17 which receives the hub, 18 shots for attachment of the non-rotating parts and in particular the brake housing of a disc or drum brake, and furthermore a hinge eye 19 for the required at a trailing steering axle tie rod.
- the above-described articulated connection between the steering knuckle and axle stalk is characterized by a particularly low overall height.
- the ride height of a so equipped trailer vehicle can be kept low, if, as the drawing shows, the axle journal 17 is higher than the above-described housing of the steering arm.
- the compact design also contributes in particular to the fact that the axle body 3 has an offset 20 in the region of the transition to the axle fist 13. This is an offset in the vertical direction and of such a size that the wave profiles 4a, 4b are approximately half the height H of the axle cross-section. This causes at the same time that the center lines of axle body 3 and journals 17 are at almost the same height.

Abstract
Description
Die Erfindung betrifft eine Lenkachse, insbesondere Nachlauflenkachse für ein Anhängerfahrzeug, mit einem in einer Achsfaust endenden Achskörper und einem mittels eines Bolzens gelenkig unter der Achsfaust gelagerten Lenkschenkel mit dem Fahrzeugrad.The invention relates to a steering axle, in particular trailing steering axle for a trailer vehicle, with an axle body terminating in an axle fist and a steering arm articulated by means of a bolt under the axle fist to the vehicle wheel.
Eine Lenkachse mit diesen Merkmalen ist aus der
Bekannt sind auch bereits Lenkachsen mit einer zwischen dem Achskörper und den Rädern angeordneten und gegenüber Lenkwinkelausschlägen wirkenden Stabilisierungseinrichtung. Derartige sogenannte Nachlauflenkachsen sind zum Beispiel in der
Die Nachlauflenkachse nach der
Die genannten Nachteile gelten auch für die Nachlauflenkachse nach der
Eine Lenkachse nach dem Oberbegriff des Anspruchs 1 ist in
Ausgehend von dem eingangs genannten Stand der Technik ist es daher Aufgabe der Erfindung, eine mit einer gegenüber Lenkwinkelausschlägen wirkenden Stabilisierungseinrichtung ausgerüstete Lenkachse zu schaffen, die
- sich leicht montieren und demontieren lässt,
- sich aus einer geringen Zahl von Teilen zusammensetzt.
- easy to assemble and disassemble,
- is composed of a small number of parts.
Zur Lösung dieser Aufgabe wird bei einer Lenkachse der eingangs beschriebenen Art vorgeschlagen, daß der Lenkschenkel unter der Achsfaust gelagert ist und der Bolzen von unten her gegen den Lenkschenkel abgestützt ist.To solve this problem is proposed in a steering axle of the type described above, that the steering arm is mounted under the axle stub and the bolt is supported from below against the steering arm.
Während der Bolzen von unten her gegen den Lenkschenkel abgestützt ist, erfolgt die Abstützung des Bolzens von oben her vorzugsweise gegen die Achsfaust. Weiterhin bevorzugt wird, dass eine der beiden Abstützungen des Bolzens unter Zwischenlage eines axial kompressiblen Federelementes erfolgt, und dass eine der beiden Abstützungen ein Axiallager ist.While the bolt is supported from below against the steering knuckle, the support of the bolt from above preferably takes place against the axle fist. It is further preferred that one of the two supports of the bolt takes place with the interposition of an axially compressible spring element, and that one of the two supports is a thrust bearing.
Gemäß einer weiteren Ausgestaltung der Lenkachse ist der Bolzen zu seiner axialen Abstützung an seinem einen Ende mit einem Gewinde versehen, auf das eine Mutter aufgeschraubt ist, wobei sich die Mutter von außen her gegen das Federelement abstützt. Auf diese Weise ist es möglich, die axiale Vorspannung des kompressiblen Federelementes, und damit auch die Rückstellkraft der Stabilisierungseinrichtung stufenlos einzustellen. Insbesondere lässt sich die über die Mutter auf das Federelement einwirkende Vorspannkraft abhängig vom jeweiligen Achstyp bzw. Fahrzeugtyp vorwählen, bevor die Mutter mittels einer geeigneten Verdrehsicherung endgültig fixiert wird. Als Schraubelement kann anstelle der Mutter auch eine Schraube verwendet werden, die dann in ein korrespondierendes Innengewinde des Bolzens eingreift.According to a further embodiment of the steering axis of the bolt is provided for its axial support at one end with a thread on which a nut is screwed, wherein the nut is supported from the outside against the spring element. In this way it is possible to adjust the axial bias of the compressible spring element, and thus the restoring force of the stabilizing device continuously. In particular, the preload force acting on the spring element via the nut can be preselected depending on the respective axle type or vehicle type, before the nut is finally fixed by means of a suitable rotation lock. As a screw, a screw can be used instead of the nut, which then engages in a corresponding internal thread of the bolt.
Zur Einstellung der Vorspannung auf den exakt gewünschten Wert ist es wichtig, das Schraubelement mit einem bestimmten Drehmomentwert anzuziehen. Um dies unabhängig von dem jeweils zur Verfügung stehenden Werkzeug zu erreichen, kann die Mutter selbst mit Mitteln zur Begrenzung des maximalen Anzugsmomentes versehen sein. Eine derartige Drehmomentmutter ist, allerdings in der Ausführung als zentrale Achsmutter, aus der
Hinsichtlich der Wellenprofile wird mit einer weiteren Ausgestaltung vorgeschlagen, dass diese an zwei sich gegeneinander abstützenden Druckscheiben ausgebildet sind, und dass die Druckscheiben gleichgestaltet sind. Die dem Einlenken des Fahrzeugs entgegenstehende Kraft ist von der Steigerung der einzelnen Flanken des Wellenprofils abhängig, so dass allein über die Geometrie eines solchen Wellprofils für verschiedene Anwendungen auch unterschiedliche Einlenkeigenschaften der Nachlauflenkachse festlegbar sind. So können beispielsweise bei Fahrzeuganhängern zum Transport sehr schwerer Lasten Wellprofile geringerer Steigung verwendet werden, als bei Anwendungen mit weniger schweren Transportgütern.With regard to the wave profiles is proposed with a further embodiment that they are formed on two mutually supporting pressure plates, and that the pressure plates are the same shape. The vehicle counteracting the turning of the vehicle is dependent on the increase of the individual flanks of the wave profile, so that only on the geometry of such a corrugated profile for different applications and different Einlenkeigenschaften the trailing steering axle can be fixed. For example, in trailers for transporting very heavy loads, corrugated profiles of lesser pitch can be used than in applications with less heavy goods to be transported.
Durch Verwendung zweier gleichgestalteter Druckscheiben lassen sich die Herstellungs-, Vertriebs- und auch Lagerhaltungskosten reduzieren.By using two identically designed pressure plates can reduce the manufacturing, distribution and storage costs.
Mit weiteren Ausgestaltungen der Erfindung wird vorgeschlagen, dass sich die Drehlagerung innerhalb des Lenkschenkels befindet, und dass der Bolzen ein gewichtsreduzierter Hohlbolzen ist.With further embodiments of the invention, it is proposed that the rotary bearing is located within the steering arm, and that the bolt is a weight-reduced hollow bolt.
Um die an der Drehlagerung wirkenden, erheblichen Momente sicher aufnehmen zu können, sollte das Verhältnis der Höhe der Drehlagerung zu deren Durchmesser weniger als 2 betragen. Optimal ist ein Verhältnis von 1,5 plus/minus 0,2.In order to safely absorb the significant moments acting on the pivot bearing, the ratio of the height of the pivot bearing to its diameter should be less than 2. Optimal is a ratio of 1.5 plus / minus 0.2.
Ferner wird vorgeschlagen, dass an dem Lenkschenkel Aufnahmen für das Bremsgehäuse einer Scheiben- oder Trommelbremse einstückig angeformt sind. Der Lenkschenkel ist auf diese Weise ein integriertes Bauteil, an dem infolge seiner einstückigen Bauweise alle wichtigen Funktionselemente konstruktiv realisiert sind.It is also proposed that on the steering arm receptacles for the brake housing of a disc or drum brake are integrally formed. The steering arm is in this way an integrated component to which all important functional elements are structurally realized as a result of its one-piece design.
Von besonderem Vorteil ist eine Ausgestaltung der Lenkachse, bei der der Achskörper im Bereich des Übergangs zur Achsfaust in vertikaler Richtung verkröpft ist. Eine solche Verkröpfung hat große Vorteile in Bezug auf die Bauhöhe der Lenkachse, woraus sich wiederum Vorteile für die Gestaltung der mit der Lenkachse ausgebildeten Fahrzeuge ergeben, z.B. hinsichtlich der Fahrzeughöhe. Vorzugsweise wird die Größe der Verkröpfung des Achskörpers so gewählt, dass sich die Wellenprofile in Höhe etwa der halben Höhe des Achskörperquerschnittes befinden.Of particular advantage is an embodiment of the steering axle, in which the axle body is cranked in the vertical direction in the region of the transition to the axle fist. Such cranking has great advantages in terms of the height of the steering axle, which in turn results in advantages for the design of the vehicles formed with the steering axle, e.g. in terms of vehicle height. Preferably, the size of the offset of the axle body is chosen so that the wave profiles are at the height of about half the height of the Achskörperquerschnittes.
Weitere Merkmale und Vorteile ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnungen, in denen eine bevorzugte Ausführungsform einer Nachlauflenkachse lediglich beispielhaft dargestellt ist. Die einzige Zeichnung zeigt eine teilweise geschnittene Darstellung einer nicht vollständig dargestellten Nachlauflenkachse, vorzugsweise für einen Nutzfahrzeug-Anhänger.Further features and advantages will become apparent from the following description of the accompanying drawings, in which a preferred embodiment of a trailing steering axle is shown by way of example only. The single drawing shows a partially sectioned view of a not fully shown trailing steering axle, preferably for a commercial vehicle trailer.
Das Drucklager 4 wird durch zwei gegeneinander verdrehbare Wellenprofile 4a, 4b gebildet, die sich in der Ausgestaltungsform gemäß
Mit zunehmendem Hub wird ein zwischen dem Lenkschenkel 1 und einer Mutter 6 angeordnetes Federelement 5 aus Gummi oder Elastomer zunehmend gestaucht. Entsprechend erhöht sich die Rückstellkraft an dem durch die Wellenprofile 4a, 4b gebildeten Drucklager. Die maximale Einfederung des Federelements 5 kann auch als Hubbegrenzung dienen, wobei der maximale Kompressionsweg kleiner als die Höhe der sich gegenüberliegenden Wellenberge der Wellenprofile 4a, 4b ist, um ein Überdrehen zweier Wellenberge ausschließen zu können. Überdrehen zwei Wellenberge, so wäre das erfindungsgemäße Rücklenken nicht mehr möglich.With increasing stroke between the steering arm 1 and a
Der als Hohlbolzen ausgebildete, durchgehende Bolzen 2 ist in die Achsfaust 13 des Achskörpers 3 verdrehsicher eingepresst und liegt mit einem an seinem einen Ende befindlichen radial erweiterten Bund von oben her an einer Stirnfläche der Achsfaust 13 an. An seinem anderen Ende weist der Bolzen 2 einen im Durchmesser reduzierten Gewindeabschnitt 14 auf, auf welchen die Mutter 6 aufgeschraubt und so das Federelement 5 gesichert und vorgespannt wird. Oberhalb seines Gewindeabschnitts 14 ist der Bolzen 2 innerhalb des Lenkschenkels 1 über ein Trockengleitlager 7 gelagert. Die sich mit dem Trockengleitlager in Drehkontakt befindende Mantelfläche des Bolzens 2 ist zumindest im Bereich des Trockenlagers 7 und entsprechend dem maximalen Hub des Drucklagers 4 von hoher Oberflächenqualität. Da das Trockengleitlager 7 ohne zusätzlichen Schmierstoff betrieben wird, ist der Lenkbolzen in diesem Bereich korrosionsbeständig ausgeführt, da der sonst durch den Schmierstoff erreichte Korrosionsschutz entfällt.Trained as a hollow bolt, continuous bolt 2 is pressed against rotation in the
Wie darüber hinaus zu erkennen ist, besteht das Trockengleitlager 7 im wesentlichen aus einer die mechanische Stabilität des Trockengleitlagers 7 bestimmenden Hülse 9, einer innen in der Hülse durch eine PTFE-Hülse (Polytetrafluorethylen) gebildeten Gleitschicht 8 sowie zwei an den stirnseitigen Enden des Trockengleitlagers 7 angeordneten Dichtringen 10a, 10b. Die aus Metall bestehende Hülse 9 sitzt durch Presssitz in der Bohrung des Lenkschenkels 1.As can also be seen, the dry sliding bearing 7 consists essentially of a mechanical stability of the dry sliding bearing 7 determining
Die in der Hülse 9 sitzende Gleitschicht 8 wird durch eine ein- oder zweistückige PTFE-Hülse gebildet, da PTFE für einen solchen Einsatz aufgrund seiner Stoffeigenschaften in besonderer Weise geeignet ist. Insbesondere ist die Oberfläche der PTFE-Hülse von hoher Qualität, wodurch die ohnehin geringen Haftreibungswerte der PTFE-Hülse gegenüber dem ebenfalls durch eine hohe Oberflächenqualität gekennzeichneten, den Gleitpartner bildenden Bereich der Mantelfläche des Bolzens 2 sehr gering sind. Aufgrund der hervorragenden Langzeittemperaturbeständigkeit des Werkstoffs PTFE sind derartige Trockengleitlager 7 über einen Temperaturbereich von -50 bis 140°C betreibbar. Ein weiterer wesentlicher Vorteil des Werkstoffs PTFE ist dessen chemische Beständigkeit gegenüber allen Medien, denen die Nachlauflenkachse während des Betriebs ausgesetzt ist. Außer PTFE eignen sich als Trockengleitschicht auch andere Kunststoffe, z.B. alle Trockenlauf-Eigenschaften aufweisenden Plastomere und Duromere.The seated in the
Die Dichtringe 10a, 10b sind zwischen der Stirnfläche der Gleitschicht 8 und einer Einbördelung der Außenhüllle 9 axial fest eingespannt. Ferner sind an den Dichtringen 10a, 10b in Richtung der Mantelfläche des Bolzens 2 vorstehende Lippen ausgeformt, die während der Dreh- und Axialbewegung des Bolzens 2 eine wirkungsvolle Sicherung des Gleitlagers gegenüber Verunreinigungen darstellen.The sealing rings 10a, 10b are clamped axially fixed between the end face of the sliding
Während sich der Bolzen 2 von unten her über den Gewindeabschnitt 14, die Mutter 6 und das Federelement 5 gegen das Gehäuse des Lenkschenkels 1 abstützt, stützt sich der Bolzen 2 von oben her an der Achsfaust 13 ab. Hierzu ist der Bolzen 2 am oberen Ende mit einem fest angeformten Radialbund 15 versehen. Da zwischen dem Federelement 5 und der Unterseite des Gehäuses des Lenkschenkels 1 eine Relativbewegung auftritt, befindet sich dort ein weiteres Axiallager 16, vorzugsweise ein flaches Axialgleitlager.While the bolt 2 is supported from below via the threaded
Einstückiger Bestandteil des Lenkschenkels 1 sind verschiedene konstruktive Elemente, wie sie im Zusammenhang mit der Radführung sowie der Radbremse benötigt werden. Dies sind neben dem eigentlich Achszapfen 17, welcher die Radnabe aufnimmt, Aufnahmen 18 für die Befestigung der nichtdrehenden Teile und insbesondere des Bremsgehäuses einer Scheiben- oder Trommelbremse, sowie femer ein Gelenkauge 19 für die bei einer Nachlauflenkachse erforderliche Spurstange.Integral part of the steering arm 1 are various structural elements, as they are needed in connection with the wheel and the wheel brake. These are in addition to the
Die voranstehend beschriebene gelenkige Verbindung zwischen Lenkschenkel und Achsfaust zeichnet sich durch eine besonders geringe Bauhöhe aus. Zudem kann auch die Fahrhöhe eines so ausgerüsteten Anhängerfahrzeuges gering gehalten werden, wenn sich, wie die Zeichnung dies erkennen lässt, der Achszapfen 17 höher befindet, als das voranstehend beschriebene Gehäuse des Lenkschenkels. Zur kompakten Bauform trägt insbesondere auch bei, dass der Achskörper 3 im Bereich des Übergangs zu der Achsfaust 13 eine Verkröpfung 20 aufweist. Es handelt sich hierbei um eine Verkröpfung in vertikaler Richtung und von solcher Größe, dass sich die Wellenprofile 4a, 4b in Höhe etwa der halben Höhe H des Achskörperquerschnittes befinden. Dies bewirkt zugleich, dass sich die Mittellinien von Achskörper 3 und Achszapfen 17 auf nahezu der selben Höhe befinden.The above-described articulated connection between the steering knuckle and axle stalk is characterized by a particularly low overall height. In addition, the ride height of a so equipped trailer vehicle can be kept low, if, as the drawing shows, the
